SPEGIFICATION'forming part of LettersPatent No. 624,840, dated May 9, 1899.

Application filed October 27, 1898. Serial No. 694,679. (No model.)

To all whom t may concern:

Be it known that I, STEPHEN S. MILES, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of over the fire pumps or forces the boiling wa# ter up through spouts on top of the clothes,

4through which it gravitates, to be again forced through the spouts.

My invention also consists in certain details of form and arrangement whereby the area of the passages or spouts is automatically controlled to circulate the maximum quantity of water, all of which will be hereinafter more A fully set forth.

In the accompanying drawings, forming part of this specification, Figure l represents a top plan view of my boiler, partly in section, on -line 'a z, Fig. 2. Fig. 2 is a central vertical section on line o o, Fig. l. Fig. 3 is a section on line oc x, Fig. 2. Fig. 4 is a perspective view of a modification of the exit of the spout. Fig. 5 is a perspective view of a modification of the conduits from the boiler to the chamber below the false bottom. Fig. 6 is a section similar to Fig. 2, showing a modification of the inlet from the lower chamber into the spouts.

A represents the main boiler-compartment, and B a chamber separated from the main compartment by a false bottom b, which is provided with perforations b', distributed evenly over its surface in rows. The water from the main compartment gravitates through the 'clothes and passes through these perforations into the chamber B.

C represents conduits open at both ends for discharging the Water as it comes through the perforations toward the inlets of the spouts D, up which it is driven by the steam generated in chamber B, to be again passed through the clothes.

E represents an automatically adjustable o1' yielding cap at the exit-orifice to prevent the escape of the steam without driving the water out with it. The size of the orifice in the exit-spouts to produce good results should be proportioned to the amount of steam being generated, which in turn depends upon the amount of re in the stove, and if the orifice is too large the steam 'escapes by itselfl without forcing any water out the spouts; but with a yielding cap the oriiice is automatically ad.h justed to the amount of stearn'being generated. As shown in Figs. l, 2, and 3,this cap consists of a strip of sheet metal secured to the wall of the boiler and its free end allowed to yield under the pressure from within. In Fig. 4 I have shown a modification in which the cap E' is hinged to the wall of the boiler and is held by a weight e against the pressure from within.

The conduits C (shown in Figs. l and 2) are V-shaped gutters or channels open at both ends and slightly open at the bottom, so that the bulk of the Water passing down through the perforations b is not mixedI directly with the boiling water on the bottom of this chamber to prevent rapid ebulli-tion, but is conveyed along the .gutters and up the spouts again. In Figs. and 6 Ihaveshown a modification of this conduit c', which is not open at the bottom, but open at each end.

As shown in Fig. 2, the inlet of the spouts consists of a simple perforation in the false bottom, through which the water and steam rush together up the spout. In Fig. 6 I have shown a modification of this inlet in Which a tube G is exten-ded down a short distance from the false bottom and a check-valve H provided to prevent the return of any Water which may have been forced into the spout. When this form is employed, the steam collects below the false bottom and forces the water up the spout until the water is lowered su fficiently to permit the steam to pass up the spout and escape. i The Valve H may be employed in the form Fig. 2 or-the tube G may be employed Without the valve.

Having described my invention, what I claim isl. In a washboiler a main compartment, a chamber located beneath said compartment and separated therefrom by a perforated partition, spouts leading from said chamber to the upper part of the main compartment, gutters or conduits beneath the perforations in IOO said partition open at the end and directing the Water from said perforations to the inlet of the spouts, exit-tubes G projecting down from said false bottom, and check-valves H,

`substantially as and for the purpose set forth.

2. In a Washboiler a main compartment, a

chamber located beneath said compartment and separated therefrom by a perforated paltition, spouts leading from said chamber to the upper` part of said compartment, gutters 1o or conduits beneath said perforations open at the end and directing the Water from said perforations to the inlet of the spouts, and a check-valve at the inlet of said spouts, substantially as specified.

In testimony whereof I have hereunto set x5
